SAMUEL B. DAVIS, OF HAMBURG, IOIVA, ASSIGNOR OF ONE-HALF HIS RIGHT TOMETOALF 85 BROTHER, OF SAME ILAOE.

IMPROVEMENT IN CORN-PLANTERS.

Specification forming part of Letters Patent No- I4'7JOS, dated February3, 1874 application filed November 19, 1873.

To all whom it may concern:

Be it known that I, SAMUEL B. DAVIS, of Hamburg, in the county ofFremont and in the State of Iowa, have invented certain new and usefulImprovements in Corn-Planters; and do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings and to the letters of reference markedthereon, making a part of this specification.

The nature of my invention consists in the construction and arrangementof an attachment for corn-planters for dropping the corn and checkingthe ground, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, in whichFigure 1 is a plan view of a corn-planter embodying my invention. Fig. 2is a side elevation of the same; Fig. 3, a rear elevation with the rearpart of the truck removed; and Fig. 4 is a vertical section through oneof the seed-hoppers.

A represents the frame-work, with runners B B, hoppers O O, axle D, andwheels E E of a corn-planter, constructed in any of the known and usualways. In the bottom of each hopper 0 are two apertures, a a, throughwhich the corn falls down onto a circular disk, G, and into apertures 12bin the same. This disk is pivoted in the center, and, being turned acertain distance back and forth on its pivot, the apertures b b arealternately brought over the upper end of the shoe or conductor, and thecorn dropped into the ground. On the edge of the disk G, opposite theapertures b b, is a projectiomd, and said projections on the two disksare connected by a slide, H, which passesacross the frame A. On the mainframe A is an additional frame, composed of two horizontal parallelbars, I I, one above the other, and connected by suitable upright posts.011 opposite sides of the lower bar I are pivoted two levers, J J, thelower ends of which enter staples or loops 0 6, attached to the slidemeans of pins 00 a2, projecting at suitable distance apart from anendless chain, f, that passes around two toothed wheels, k 70, uponupright shafts in the ends of the bars I I. On the same upright shaftsare elongated pinions m m, as shown in Fig. 3.

The dropping mechanism thus constructed is operated by the followingmeans: K represents a shaft, having its inner end placed in aswivel-eye, n, which is arranged in the center on top of the top bar I.On the outer end of this shaft is a wheel, composed of a hub, L, withsix radiating arms, M M, at equal distances apart. On the outer ends ofalternate arms are secured segments N N which are provided with teeth ontheir outer edges, so as to enter the ground and revolve the wheel andshaft when the machine moves forward. Upon the outer ends of the otheralternate arms are secured markers 0 O, which, when the machine is inmotion and the wheel revolves, mark or check the ground for the plantingof the corn. On the shaft K is secured a wheel, P, which is cogged ortoothed on its side, and gears with the elongated pinion m .at one endof the frame I I. As the shaft K revolves, as above already described,the wheel 1? causes the endless chain f to revolve, and the pins 00 w inthe same to operate the levers J J, so as to move the slide H back andforth, and thereby rock the dropping-disks G" G on their pivots to dropthe corn.

The shaft K may be thrown to either side, so as to bring the wheel L M N0 either to the right or left of the machine, to mark or check theground 011 either side desired and drop the corn, the wheel I? engagingwith either of the .elon gated pinions m. The shaft K is supported in aforked upright, R, and held down in the same by a pin, i. There is oneof these forked uprights on each side attached to the hoppers O O.

In going to and from the field, the shaft K is elevated to an uprightposition, slid through the swiveled eye a, and screwed into a nut, 10,which is embedded in the lower bar I, thereby holding the shaft firmlyin this position.

l'[a\"i1igtlu1s fully described my invention, what I claim as new, anddesire to secure by l'ietters Patent, is-

1. The combination, with the dropping mechanism of a corn-planter, ofthe slide H, with loops or staples 0 e, pivoted levers J J, and theendless revolving chain f, with pins :20 00, all constructedsubstantially as and for the purposes herein set forth.

2. The shaft K, with sectional checking or marking Wheel L M N O andcog-wheel P, in combination with the pinions m m, Wheels 757.,

SAMUEL B. DAVIS.
